About Mineola

Park

Mineola Park, located between Old Country Road and Jericho Turnpike, is a residential and commercial Carle Place neighborhood with a pocket-park feel and a rail-adjacent rhythm. The neighborhood’s character concentrates around the Old Country Road and Glen Cove Road corridor, where low-slung storefronts, diners, and service shops set a steady, daytime hum. Housing reads as classic Nassau County: tidy capes and ranches on tree-lined blocks, with a few small multifamily buildings near the busier roads. Mineola Memorial Park and nearby playing fields add open green breaks between retail strips. The Long Island Rail Road at Carle Place and Mineola stations frames commuting patterns and keeps the streetscape active. Local staples like Carle Place Diner, The Carle Place Inn, and Westbury Music Fair anchor the area’s off-hours scene.
